To ALL wHoM 1T MAY concerns;

Be it known that I','CHARLns WENDELL, of the cityvof Albany, in thel county of Albany,'and State of' New York, have inventeda new and improved Cushion for School-Slates;v and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which?- i i Figure 1 is a perspective view of a school-slate, having my improved cushion applied to its frame. y Figures 2 and 3 are enlarged views oi' portions of a slate-frame and slate, showing the manner of applying the cushions.

Similar letters'of reference' indicate corresponding parts in the several figures.

Thi'siknvention -relates to a new and useful'improvement on elastic cushions for school-slates, which cushions are designed for preventingslate-frames from scratching the surfaces of desks, also for preventing noise occasioned by the handling of slates upon desks or tables, and alsoffor aifording protection to slates when they are allowed to fall. v v v Prior to my invention, slate-frames have been providedwith elastic cushions by'inserting cylinders of rubbei` through holes made throngh the'frames, so'that the ends of the cylinders are exposed beyond the surfaces oi' the frames; The corners of slate-frames have also been covered with rubber and other soft yielding substances,

which formed protectingcushions for the slate. A patent has also' been granted for rubber cushions, of a buttonshape, connected together in pairs, and adapted for being secured to a Aslate-frame by inserting one ofthe buttons of cach pair of cushions through a hole` made throughv a slate-frame.

The object of my invention and' improvement is to so apply rubbe'r cushionsfor protectors to a slate-frame that they Vcannot be removed from their places unless they are either broken and destroyed, or the slate-frame detached from the slate.

To eiiect this object, the natureot` my invention consists in the application, to the frame of a slate or other writing-tablet having a frame secured around it, of VIndia-rubber bands, which encircle the frame, and are` con. fined inplace' byjthe edge ot the slatel or writing-tablet in the act of securing the `frame in' its place, as will be hereinafter explained. i i

To enable others skilled in the art to understand my invention, I will describe its construction and operation. In the accompanying drawings, A represents a writing-tablet, B a frame surroundingrthc same, and .C C GC Your India-rubber hands lor rings, which encircle the frame near .its four corners, and form protecting cushions for the tablet and frame. l

VThe frame B is made of four strips of wood or other substance jointed together and fastened at their ends,

and grooved at a, tigf 3, to receive the edges of the tablet A, andv hold this tablet firmly in place within the frame, in a manner common tothe construction of most of the school-slates in use. I

Before applying the frame B around the tablet A, the elastic handsor cushion-rings C are slipped upon the frame, andadjusted in their proper' places at or'Y near the corners of this frame, or at any otherdesired-i points. -Thc tablet is then introduced inl itsplace within the frame, and theedges of 'this tablet confined tightly i in the grooves a, inl doing which Vthose portions of the cushion-rings C which cross Said grooves, will be Icompressed'and forced therein by the edges of the tablet, thereby confining them iirmlyin their places 'when the frame is secured in its place. n I

FigureS is a sectionalwiew, showinga rubber cushion confined inplaceby thc edge ci' the tablet entering its `groove in a portion of the frame. Y l

-It will be seen from this description that the cushion-rings require `no other fasteningthan that aiorded by the edges of the tablet enteringthe grooves inthe frame. Neither holes, notches, nor cement are req'uired`- to fasten the cushions in their places, and when applied to the frame the cushions present protecting surfaces i both for the sides and outer edges of the frame, and also protect the tablet itself from asudden. concussion should the slate fall, as port-ionsot` the cushion-rings are interposed between the edges of the-tablet and its I do not confine myself to the flat shapenf the cushion-rings shown in the drawings, as these rings may VV leemfr1n hunr1 01:semicirculai in cross-section', and they may be arranged in any suitable manner upon the slate-frame. l

Having described my invention, what l claim as new, and desire to sccure by Letters Patent, is- The application of cushion-rings C to the frzmie of a, slate or Writing-tablet, substantially in the mannei' and for the purpose described.

' CHARLES WENDELL.
